Is "participating remotely" the same thing as "goofing off at work"? If so, I'm doing it. One more question: is there a good way to test almost-equals, for the numerical approximation? Or do I just do abs(x - y) < epsilon?

OK, make ptestlong finished. There were failures, but none of them are due to this ticket specifically as far as I can tell. They are all due to the maxima-5.24 spkg I believe. I need to look into #12094 to be sure but it's too late to do that tonight..
